To all whom it may concern: .A

Be it known that I, HowAnp C. MAnMoN, a citizen of the United States, residing at Indiana Sta-te o Indiana, have invented certain r and useful Improvements in Controllers, of which the following is a speciication.

The object of my invention is to produce f a device for shifting speed chan ing mechanism to any one of its severaI positions by-the manipulation of a sin le element.

A further object is that t e construction be such that any desired portion of the mechanism may be operated by a direct movement of the aforesaid single element Without operating other portions.

The accompanying drawings illustrate my invention.

Figure 1 is a side elevation of an apparatus embodying my invention; on line 2 2 ofFig. 1; Fig. 3 section on line 4 4 of Fig. 2; tion on line 5 5 of Fig. 6, illustrating a modia 1an; Fig. 4 a.

ig. 5 is a seccation; Fig. 6 a section on line 6 6 of'F` 5; Fig. 7 a plan, in partial horizontal section of the parts shown in 5, and F` .8 a partial plan of the parts shown parly in section u1 Fig. 7. Y

In Figs. 1 to 4, 10 indicates a shaft provided at one end with a plate 11 having an inturned upper flange 12 provided in its inner edge with a notch I3. Secured to the other end of shaft 10 is an arm 14 to which may be connected a member for shifting desired elements of a speed changing gearing (not shown).

Sleeved upon shaft 10 is a sleeve 15 w 'ch at one end carries a plate ,16 similar to p ate 11. Plate 16 is provided at its outerend with a flange 17 which projects towards the flange 12 of plate 11 and is provided on its inner edge with a notch 18 similar to the notch 13. Journaled' upon shaft 10 hetween the hubs of .the plates 11 and 16 is a collar 20 rovidedwith a pivot pin 21 which lies at rig t angles to theshait 10. Pivoted upon the Jivot 21 is the inner end of a hand lever'` 22 w ch extends outward between the flanges 12 and 17 and is adapted to enter either one of the notches 13 or 18, tlc s.:- ran ement bein such that, by swinging the ever 21 to t e-right or left in Fig. 2 it may be thrown into either the notch 13 or 18 and then, by swinging the same forward Fig. 2 a section' polis, in the county of Marion f ld r In the drawings, the sleeve 15 is journaled l or back on shaft 10 as an axis, may rock either the shaft 10 or the sleeve 15 in either direction and thus swing either arm 14 or arm 19 in either direction.

l in the main frame 25 and, in order that the ,l parts may be locked in neutral position I provide the following construction: Arranged between the lever 22 and plate 11 is an arc bar 30 having a notch 31 formed in its outer face, said notch being adapted to receive a spring linger 32 carried by the inner face of plate 11 and lying between a pair of lips 33 integral with plate 11. Simiarly arranged between lever 22 and plate 16 is an arc-bar 34 provided in its outer face with a notch 35 adapted to receive a spring finger 36 attached to the inner face of plate 16 and lying between a pair of lips 37. The two spring fingers 32 and 36 are projected into plosition to be engaged by the hand lever 22 W en it is shifted to the ri ht or left in Fig. 2 so that said lingers may e forced out of the notches 31 or 35 by the inward Inovernent of the hand lever.

In the construction shown in the first four figures of the drawings, four possible positions may be had with the hand lever, t'. e., three speeds ahead and one reversed, or `any other combination desired.

In Figs. 5 to 8 inclusive I show a construction capable of six positions, and the construction is as follows: The shaft 50 may be provided at one end with an arm 51 and at the other end with a plate 52 similar to the plate 11 and provided with a notch 53 in its upper flange. Sleeved upon shaft 50 is a Sleeve 54 whlch is provided at one end with an arm 55 and at the other end with a'hub 56. Sleeved upon the sleeve 54 is a sleeve 57 provided at one end with an arm 58 and at the other end with Va plate 5S) similar to thc plate 1G and provided in its ulppcr flange with a notch 6() which practical r registers with thc notch 53. 'lhe upper flanges oi the plate 52 and 59 project toward each other, but sufficient room is left between them for the passage of the hand lever 61 which is ivoted on the )ivot 62 (at right angles to the s it 50) carried by the collar 63 whinh ieiournaled on shaft 50. Hub 56 is provided with a pair of diverging arms 64 and 65 which, at their outer uppercnds aro provided with ap roach-3 ing fingers 64 and 65 respectively w ich lie between the inwardly rojecting flanges of the plates 52 and 59, tic inner ends of said fingers approaching each other to substantia ly the same distance as the width of the adjacent notches 53 and 60. The arms 64 and 65 are first diverged in order that there may be freedom of `movement of the hand lever 61. ln this frame the plates 52 and 59 may be locked in their middle positions to arc-bars 70, similar to are-bars 30 and 34, in the manner already described, the spring' fingers 7l carried by the lates 52 and 59 serving to normally hold t 1e hand lever 61 in its medial position in the manner already described. ln this form the hand lever 61 may be shifted forward or backward in its medial ostion in which case it will pass between t ic inwardly rejecting ilanves of the plates 52 and 59 an will engage the `lingers 64' or 65. By swinging lever 61 to the right in Fig. G, it may bc t irown into notch 53 and then, by swinging on shaft 50, may be used to rock shaft 50, or, by shifting the lever to the left it will be thrown into notch 60, whereupon the lever may be used to rock sleeve 57.

I claim as my invention :n

1. In a controller for motor vehicles, the combination with a pair of nested co-axial controlling elements, of an operating lever coaxial and nested therewith and having a joint permitting movement of said operatmg element in op osite directions toward either of said contro ling elements, said controlling elements cach having a portion ada ted to receive a portion of the operating e ement, a stationary member extending between 'the operating clement and each controlling element, and a spring catch carried by each controlling element and ada ted to engage the adjacent 'stationary member to normal -y prevent movement of its controlling element and arranged in the path of transversemovement of the operati-ng element, substantially as described.

2. ln a controller for motor vehicles, the combination with a pair of nested coaxial controlling elements, of an operating lever coaxial and nested therewith and having a joint permitting movement of said operating element in op osite directions toward either of said contro ling elements, said controlling elements each havi a portion adapted` to receive a portion of t e operating element, a stationary memberextending between the operating element andfeach controlling clement, a spring catch carried yby each controlling element and adapted to engage the adjacent stationary member to normally prevent movement of its controlling element. and arran ed in the path of transverse movement of t e operating element, and a third element coaxial and nested with the firstmentioned controlling elements and lying between the same in position'tobe engaged' a swinging movement of the operating b 4eliament between the two first mentioned controlling elements.
